In 1913, Mercer began work on a six-story poured-in-place concrete castle to house them near his home in Doylestown, Pennsylvania.
More than 30,000 objects from Mercer’s collection—from tiny butter molds to car-sized threshing machines—are displayed within the soaring arches of his eccentric structure.
